Postfix with Cyrus SASL

[Shawn Barnhart]

I'm running a recently built 6.2 stable build (which uname calls 
6.3-PRERELEASE) and
Postfix built from ports with the Cyrus SASLv2 option.  Postfix works 
fine, including TLS but SASAL authentication logs "file not found" errors.

Jan  9 17:14:10 postfix postfix/smtpd[48488]: warning: SASL 
authentication failure: cannot connect to saslauthd server: No such file 
or directory
Jan  9 17:14:10 postfix postfix/smtpd[48488]: warning: 
unknown[192.168.1.152]: SASL LOGIN authentication failed: generic failure

I'm not sure which file or directory is missing.  The docs on this are 
sketchy, most of what is listed is way out of date, and the most up to 
date docs, http://www.postfix.org/SASL_README.html isn't terribly 
platform specific.

Its not entirely clear if I need other SASL components; the entire Cyrus 
SASL package appears installed.
